William (Bill) Haddock took out the lease around 1934. While most prospectors focussed on the ironstone bodies around Tennant Creek when looking for gold, Haddock wandered out west into the spinifex plains, and followed a small jasper outcrop. This rock was not normally associated with gold, however it was found to be in this area, with also quartz and hematite.
Haddock persisted working alone sinking a shaft through hard rock. He was elderly already by this stage, and it must have been hard work, blasting the rock, then constantly climbing up and down the shaft to haul out the rock. For four years he worked finding no gold. He sank a new shaft to 40 feet, and on connecting the two 'opened up a wonderful face of picture stone'.
From this ore shoot, in 1938, from the No. 2 government battery he obtained 500 ounces of gold from 67 tonnes of ore, worth at the time 4544 pounds. It appears to have been an isolated find as no further crushings were found. Explored by the North Flinders Mines/Posgold Central Joint Venture 1992-1995, and drilling found relentless porphyry and no gold. The site is at the far western part of the Tennant Creek Goldfield, about 15 kilometres west of the town.
